>He's a massive jackass too, but you can't fire people on the spot for being a massive jackass without a lot of evidence to back it up.
The implication of this is that you also have experience at Uber working with somebody who is unfireable despite being a "massive jackass" and engaging in sex discrimination against at least one female employee there, while you were around as a witness. It's good that you spoke up when he acted like that, I don't mean this as a personal attack on you or your coworkers specifically. But your anecdote here reads like one more story confirming issues with Uber's management/HR, even though you've intended it otherwise.
